National Electrical Safety Code Continues to Be Refined

National Electrical Safety Code Continues to Be Refined

Work is well on its way toward the next, 2017 edition of the code.

Key changes that were introduced in the current, 2012 edition of the NESC include:

  • clarifications where the NESC applies in relation to the NEC
  • revised requirements around equipment grounding
  • clarification of certain fencing requirements in substations
  • illumination requirements for generating stations and substations
  • new arc flash protection requirements for worker exposures below 1000 volts and changes to minimum approach distance (MAD) tables

Now, work is well on its way toward the next, 2017 edition of the code, according to a report from Transmission & Distribution World. Proposed changes to adapt for new challenges and technology innovations are currently under consideration.

T&D World's article looks at how the NESC steadily evolves to improve protection for utility linemen, field superintendents and the public. It discusses changes under consideration for the 2017 NESC, the methodical process of evolution, and contributions to the safety of utility workers and the public.

Initially introduced in August 1914, the NESC has remained a relevant, essential resource for utility linemen, field superintendents and the public even 100 years after its introduction, according to the article, because of a broadly shared commitment to keep it up to date through a proven process of constant improvement. As soon as one edition of the code is released, work on the next edition commences.
